Following the service, the royal family posed for official portraits taken by photographer Matt Holyoak in the Morning Room at Clarence House.

It was almost the same line-up as Princess Charlotte's christening in 2015 and Prince George's in 2010, with one extra face - Prince Harry's new wife, Meghan. Meanwhile, the Queen and Prince Philip were notably absent.

There's also a portrait of the entire extended family, including the Middletons, gathered around Prince Louis, and a stunning individual photo of Kate - dressed in a long-sleeved cream Alexander McQueen dress and headpiece by Jane Taylor - holding her newborn son.

In a statement released on the eve of the christening, Kensington Palace confirmed that Louis' godparents wouldn't include either William's brother Harry or Kate's sister Pippa, with close friends and just one relative making the list.
